This site uses many images from external sources. Most of them are under Creative Commons licenses. In compliance with the license and to make it easy to find the original photos, all photos that are not personally mine are credited and linked. Most of them have been cropped or resized, but otherwise not altered.

Some may be provided by readers of the site, and those will be credited as well. If you wish to donate an image for potential use onsite, you may email me the photo and how you wish to be credited. Any owner of a photo onsite may ask for it to be taken down, or the credit altered at any time.

All graphics and art onsite, unless otherwise stated, were made by me personally. Educational graphics with my credit and site url on them may be shared on other sites so long as that credit remains. They may not be printed or used for profit. Please ask first if you want to modify a graphic for any reason.
